How to use SFTP in VBScript

Network Component provides an easy-to-use development interface to a variety of IP protocols. By using Network Component, you can very easily create or enhance applications with network features.

Network Component features the following: DNS, FTP, HTTP, HTTPs, ICMP Ping, IP-to-Country, MSN, NTP, RSH, SCP, SFTP, SNMP v1/v2c (Get, GetNext, Set), SNMP Traps, SNMP MIB, SSH, TCP, Telnet, TFTP, UDP, Telnet, Wake-On-LAN and more.

Network Component can be well integrated into any development platform that supports ActiveX objects.

The most important functions of the SFtp object are:

Step 1: Download and install the Network Component

Download Network Component from the ActiveXperts Download Site and start the installation. The installation guides you through the installation process.

Step 2: Create a new script

Create a new script using your favorite editor. You can simply use notepad. However, a VBScript editor is recommended, so you can browse through objects, objects properties and object functions.

You're now able to write a more advanced script to communicate using the Network Component.

Step 3: Create the Network Component object in VBScript

Create a new VBScript file called DEMO.VBS. It is recommended to insert the following line on top of your code:

Option Explicit

This statement requires that all variable names be defined (with the Dim statement), to avoid simple typos that can cause incredible headaches and long debugging sessions for something that should have never happened.

Now, declare the Network Component object(s):

Dim objSftp

Create the Network Component object(s) like this:

Set objSftp      = CreateObject( "AxNetwork.Sftp" )

Now, add the following lines to the file to have your first Network Component VBScript program:

WScript.Echo "Version: " & objSftp.Version
WScript.Echo "License Status: " & objSftp.LicenseStatus
